Nu Holdings Takes Flight: A Stellar Q2 Powers Stock to Five-Month High

Friday was a truly remarkable day for Nu Holdings Ltd. (NYSE:NU), the powerhouse behind the beloved digital bank, Nubank. Shares absolutely soared, leaping by more than 10% in afternoon trading to hit an impressive $15.35. For investors, this wasn't just a good day; it marked the stock's highest level in over five months, suggesting a palpable renewed confidence in the company's trajectory. And honestly, looking at their latest earnings, it’s not hard to see why the market reacted with such enthusiasm.

The real headline grabber, though, was their staggering net income for the second quarter of 2026, which hit a cool $1.1 billion – a record, no less! That’s a jaw-dropping 49% increase year-over-year when you strip out currency fluctuations. Founder and global CEO David Velez couldn't help but emphasize the milestone, noting, "Nu is now generating more than a billion dollars in quarterly net income." Alongside this, gross revenue nearly touched $5.9 billion, climbing a robust 39% compared to the same period last year. These figures paint a clear picture of a company not just growing, but thriving.

But it's not just about the money; it's about the people. Nu Holdings continued its relentless march of customer acquisition, bringing in roughly 4 million new users during the quarter. This pushes their global customer base to a colossal 139 million. Most of these, about 118 million, are in their home market of Brazil, but they’re also making significant inroads in Mexico (15.8 million) and Colombia (over 5 million). Crucially, these aren't just dormant accounts. Their average revenue per active customer (ARPAC) settled at around $17, and the monthly activity rate expanded beautifully to 83.5%, with Brazil even surpassing 86%. This means customers are engaged, using the services, and contributing to the bottom line.

Looking deeper into the financial health, Nu's gross profit swelled to $2.4 billion, a solid 43% jump year-over-year. Their return on equity (ROE) closed the quarter at an impressive 33%, showcasing stellar efficiency. Moreover, the net interest margin expanded by a healthy 180 basis points to 22.9%, with the risk-adjusted NIM climbing from 9.5% in Q1 2026 to 12.4%. Rob Livingston, Nu Holdings’ new CFO, confidently stated that this current risk-adjusted NIM is seen as sustainable, which is certainly music to investors' ears.

The credit portfolio saw significant growth too, expanding 37% year-over-year to $39.4 billion, while deposits also rose 18% to $45.3 billion. Now, it's worth noting that the 90-plus day non-performing loan (NPL) ratio did tick up slightly by 35 basis points to 6.9%. However, management was quick to attribute this largely to a seasonal migration of early delinquencies from the first quarter. On a more positive note, the leading 15-90 day NPL ratio actually improved, dipping 16 basis points to 4.8%, also attributed mostly to seasonal factors. Even their efficiency ratio, though slightly worsened quarter-over-quarter, improved nicely from the prior year.

Analyst reaction was, as expected, positive. Susquehanna, for instance, bumped up their price target on Nu Holdings to $16 from $13, while maintaining a "Neutral" rating. This kind of upgrade certainly lends weight to the company’s strong performance narrative.

What makes Nu Holdings’ performance even more striking is how it contrasts with the broader Latin American fintech landscape. While Nu shares were flying high, many of its peers were struggling. StoneCo (NASDAQ:STNE), for example, saw its stock dip 6% to $9.59, grappling with a "considerably more challenging" backdrop, a R$200 million non-recurring provision, and a 35% year-to-date decline. Elsewhere, MercadoLibre (NASDAQ:MELI) managed only a modest 1% rise, Inter & Co (NASDAQ:INTR) shares remained unchanged, and banking giant Itau Unibanco (NYSE:ITUB) even slipped by 1%. Even the broader market indicators weren’t sparkling, with the iShares MSCI Brazil ETF (NYSEARCA:EWZ) down half a percent and the Global X FinTech ETF (NASDAQ:FINX) declining by 1.33%. Nu, it seems, truly stood apart.

All in all, Nu Holdings’ second quarter of 2026 was nothing short of spectacular. With record earnings, booming customer numbers, and a clear path to sustainable profitability, Nubank is not just participating in the digital finance revolution; it’s leading the charge in Latin America, leaving many of its competitors in the dust. Investors who held on through the earlier volatility are certainly reaping the rewards now.
